What is Theraflu Daytime Severe Cold?
Acetaminophen is used to relieve pain and reduce fever.
Phenylephrine is a decongestant that helps narrow blood vessels in the nasal passages. When blood vessels are wider, it can lead to nasal congestion (a stuffy nose).
Theraflu Daytime Severe Cold is a combination medicine that helps treat headache, fever, body aches, a stuffy nose, and sinus congestion caused by allergies, the common cold, or the flu.
Theraflu Daytime Severe Cold may also be used for other reasons not mentioned in this medication guide.
